JPG Compressor Examples
The JPG Compressor reduces JPEG file sizes while maintaining visual quality. Below are examples showing quality settings, size reductions, and use cases for different types of images.
Quality Level Comparison
Original photo: landscape.jpg
Resolution: 4032 × 3024 pixels (12 MP)
Original size: 8.2 MB (camera JPEG at quality 95)
Quality 95 (original): 8,200 KB — reference
Quality 85: 2,100 KB — 74% reduction, visually identical
Quality 80: 1,400 KB — 83% reduction, excellent quality
Quality 75: 980 KB — 88% reduction, very good quality
Quality 70: 720 KB — 91% reduction, good quality
Quality 60: 480 KB — 94% reduction, slight artifacts
Quality 50: 320 KB — 96% reduction, visible artifacts
Quality 30: 180 KB — 98% reduction, noticeable quality loss
Recommended: Quality 80-85 for web photos
Example: Product Photo Optimization
E-commerce product image: product-shoe.jpg
Original: 3.4 MB, 2400×2400px, quality 92
Optimization steps:
1. Resize to 800×800px (display size)
2. Compress to quality 82
3. Strip EXIF metadata
4. Enable progressive encoding
Result: 68 KB (98% reduction from original)
Visual quality: Excellent for web display
Before: 3,400 KB
After: 68 KB
Savings: 3,332 KB per image
For a catalog of 500 products:
Before: 1,700 MB total
After: 34 MB total
Bandwidth saved per page load: ~3.3 MB
Example: Blog Post Hero Image
Hero image: article-header.jpg
Original: 5.1 MB, 5472×3648px
Optimization:
Resize to: 1200×800px (max display width)
Quality: 80
Progressive: yes
Strip EXIF: yes
Result:
File size: 142 KB (97% reduction)
Load time on 4G: ~0.3s (was ~10s)
Core Web Vitals impact:
LCP before: 8.2s (Poor)
LCP after: 1.4s (Good)
Example: EXIF Metadata Stripping
Photo taken with smartphone: vacation.jpg
File size before stripping: 4.2 MB
EXIF data found:
Camera: iPhone 15 Pro
GPS Latitude: 37.7749° N
GPS Longitude: 122.4194° W
Date/Time: 2024-07-15 14:32:08
Focal Length: 6.86mm
ISO: 64
Shutter Speed: 1/1000s
Software: iOS 17.0
EXIF size: 48 KB
After stripping EXIF:
File size: 4,152 KB (48 KB saved)
Privacy: GPS location removed ✓
Note: Always strip EXIF before publishing photos online
to avoid leaking location data.
Example: Progressive JPEG
Standard (baseline) JPEG loading:
0% → blank
25% → top quarter visible
50% → top half visible
75% → three quarters visible
100% → full image
Progressive JPEG loading:
0% → blank
10% → full image visible at low quality (blurry)
30% → full image at medium quality
60% → full image at good quality
100% → full image at final quality
Progressive JPEG benefits:
- Better perceived performance on slow connections
- Users see the full image immediately (blurry → sharp)
- Slightly smaller file size than baseline JPEG
Size comparison (same quality 80):
Baseline: 142 KB
Progressive: 138 KB (3% smaller)
Example: Chroma Subsampling Options
Image: portrait-photo.jpg (1200×1600px)
4:4:4 (no subsampling):
Full color detail preserved
File size: 285 KB
Best for: text on images, graphics with fine color detail
4:2:2 (horizontal subsampling):
Color resolution halved horizontally
File size: 220 KB (23% smaller than 4:4:4)
Best for: general photography
4:2:0 (standard JPEG subsampling):
Color resolution halved in both directions
File size: 185 KB (35% smaller than 4:4:4)
Best for: web photos, social media
Default for most JPEG encoders
Batch Compression Results
Processing product catalog: 250 images
Settings: Quality 82, strip EXIF, progressive, resize to 800px max
Results:
Total original size: 1,240 MB
Total compressed: 62 MB
Total savings: 1,178 MB (95% reduction)
Average per image:
Before: 4.96 MB
After: 248 KB
Processing time: 45 seconds
Largest savings: hero-banner.jpg
Before: 18.2 MB → After: 380 KB (98% reduction)
Smallest savings: icon-small.jpg
Before: 12 KB → After: 8 KB (33% reduction)
Note: Small images compress less efficiently
Quality vs File Size Reference
- Quality 90-100: Archival quality, large files — use for print or source storage
- Quality 80-89: Excellent web quality — recommended for hero images and galleries
- Quality 70-79: Good web quality — recommended for thumbnails and product images
- Quality 60-69: Acceptable quality — use for low-priority images or very slow connections
- Quality below 60: Visible artifacts — avoid for most use cases
Upload your JPEG images, adjust the quality slider while watching the preview, and download the optimized files. Most photos look excellent at quality 80 with 80-90% file size reduction.
